roads and bare fields from June (Dissosteira) or July (Trim- 

 crotropis) to early December. The latter species seems to 

 be seldom found away from roads except in the latter part of 

 its seasonal range, and is furthermore the only Acridiid which 

 I have noted as being attracted to lights. 



Subfamily ACRIDIINAE 



Lcptysina inarglnicolHs apparently overwinters as adult, and 

 is confined to marshes except in late fall when I have col- 

 lected it on dry ground among broom straw (Andropogon). 

 Apparently ranges through nearly the whole year. 



Of the three Schistocercse found here, alittacca occurs 

 chiefly on the uplands from early August to early October, 

 not overwintering in the adult stage like the other two species, 

 while damnified has been taken from mid-September to late 

 April, its habits in winter being similar to those of aincricana. 



S. aincricana, our third species, occurs throughout the entire 

 year, the nymphs which are dimorphic in color, some being 

 brown and others green, transform to the adults from the end 

 of August to the middle of October. The adults leave the 

 fields and take to the woods during the winter and are liable to 

 be on the wing on any comparatively warm day. In spring 

 they leave the woods and take to the fields again, being found 

 in May and June on crimson clover and grain ; about this 

 time the sexes are found in coitu. In July and August their 

 numbers rapidly diminish, but old adults were brought me in 

 September, 1907, at the same time as newly transformed speci- 

 mens. 



Of our Melanopli, atlanis occurs in grassy fields from June 

 to December, an occasional specimen lingering on till January ; 

 while fctmir-rnbriini only occurs from September to late Nov- 

 ember though very abundant in grassy fields at that season. 

 The other two common species, kcclcri and satddcri, occur in 

 or near pine woods mostly, their range being from mid-August 

 to early December, though I took specimens of the latter on 

 January 21 and 22, 1906. Our only other form pitnctulatns, 

 occurs in pine woods, but we have only taken four specimens 

 (on October 9 and 19, and November 5, 1907).
